Abstract: The aim of this work is to study the main thermoluminescent (TL) characteristics of the inorganic polyminerals extracted from dehydrated Jamaica flower or roselle (Hibiscus sabdariffa L.) belonging to Malvaceae family of Mexican origin. The TL emission properties of the polymineral fraction in powder were studied using the initial rise method (IR), finally the complex structure and kinetic parameters of the glow curves have been accurately analysed using the Computerized Glow Curve Deconvolution (CGCD) assuming an exponential distribution of trapping levels. The extension of the IR method to the case of a continuous and exponential distribution of traps is reported such as the derivation of the thermoluminescence glow curve deconvolution functions for continuous trap distribution. CGCD is performed both in the case of frequency factor, s, temperature independent and in the case with the s function of temperature.
